Application tiled October 2Q, 1587.

To LZZ whom t 17mg/ concern,.-

Be it known that l, CHARLES A. MANN, of Budalo, in the county ot' Eric and State of New York, haveinvented new and useful Improvements in Suspender-Buckles, of which the following is a specication.

This invention relates to an improvement in that class of buckles which are provided with a sliding tongue-fraine-such, for instance, as the buckle shown and described in Letters Patentof the United States, No. 312,136, granted to me February 10,18S5-the presentinvention being an improvement upon said buckle and designed especially for use ras a suspenderbuckle.

The object of my invention is to provide the buckle with simple means whereby the tongueframe can be readily shifted and locked in position without materially increasing the cost of the buckle.

The invention consists of the improvements which will be hereinafter fully described, and pointed out in the claims.

VIn the accompanying drawings, Figure lis a front elevation of my improved buckle applied to a suspender-strap. Fig. 2 is a longitudinal vertical section thereof. Fig. 3 is a front elevation of the buckle removed troni the suspenderstrap. Fig. e is asimilar View showing the tongue-frame in the position in which its tongue clears the loop through which the suspender-strap passes. Fig. 5 is a cross-section of the buckle inline a' ai, Fig. 3. Fig. G is a perspective 'view of the lever whereby the sliding tongue-frame is shifted.

Like letters of reference refer to like parts in the several ligures.

A A represent the two .loops formed at the upper and lower ends of the buckle, and which are connected by two end bars, a a, and two central or intermediate bars, ai. The loops A A and connecting-bars constitute the main frame of the buckle, and are preferably stamped in one piece out of sheet metal.

B represents the tongue portion or frame, which is arranged to slide vertically upon the central bars, a, and provided with prongs or tongues Z). The tongue-frame B is provided at its lateral edges with angular lips b, which bear against the outer side of the central bars, a, and guide the tongue-frame in its movements.

Serial No. 253,(l59. (No modcLl C represents the shifting bar or lever whereby the tongue-frame .B is moved toward and from the upper loop, A, so that its prongs b project across the loop or clear the same. The lever C is pivoted at one end to one of the end bars, d. d', and at or near its center to the tongue-frame B. The latter is pivoted to the shifting-lever C by a pin or rivet, d, which is secured to the tongue frame and passes through a longitudinal slot, e, formed in the lever. The free end of the lever G is bent around the adjacent edge of the buckle-frame, as shown ate in Fig. 5, so that the free end of the lever will be held against the buckle-frame. By this construction the tongue-frame is iirmly held against the central bars, ci, While being confined against "lateral displacement by the lips b. The central portion, c', of the lever, which lies against the tongue-frame, is raised, so as to permit the end portions of the lever to rest snugly against the buckle-frame. The bent end e of the lever forms a convenient thumb-piece for operating the lever.

f is a stop or projection arranged at the upper end of the connecting-bar u, and which prevents the downward movement ofthe shifting-lever when in an elevated position. The elasticity of the lever permits its free end to be sprung over the stop f. This stop is preferably formed by making an indentation on the rear side of the bar a.

g represents a loop formed at the lower end of the buckle-frame, below the loop A', and which is designed to receive the hook attached to the detachable suspender-ends G.

H represents the suspender-strap, which is inserted through the upper loop, A, from the rear side thereof.

Upon raising the tongue-frame by means of the lever C the prongs b project over the loop A and penetrate the suspenderstrap, thereby securely attaching the buckle to the strap. In raising the shifting-lever its free end engages behind the stop f, whereby the tongue-frame is prevented from descending and its prongs are held in engagement with the suspender. By depressing the free end of the lever the tongue-frame is lowered and its prongs are released from the suspenderstrap, thereby permitting the. buckle to be freely adjusted upon the suspender-strap.

I claim as my invention- IOO l. The combination, with the buckle-frame provided with a loop through which the suspender strap is inserted, of a sliding tongueframe attached to the buckle-frame and provided with tongues or prongs, and a shifting bar or lever pivoted to the buckle-frame and to the tongueframe, whereby thetongue-frame is moved toward and from said loop, substantially as set forth.

2. The combination, with a buckle-frame provided with a loop through which the suspender-strap passes, of a sliding tongue-frame attached to the buckle-frame and provided with tongues or prongs, a shifting-lever pivoted to the buckle-frame and to the tongueframe, whereby the tongue-frame is moved toward and from said loop, and a stop whereby the shifting-lever is locked in position, substantially as set forth.

3. The combination, with a buckle-frame composed of the loops A A and connectingbars a a a2, of a sliding tongue-frame, B, attached to the connecting-bars a a and provided with prongs b, and a shifting-lever pivoted to one of the connectingbars a a and to one end to one of the bars a a and having itsfree end bent around the edges of the buckleframe, and a sliding tongue-frame, B, pivoted to the shifting-lever C and provided with lips b' and prongs b, substantially as set forth;V

Witness my hand this 15th day of October,

1887. CHARLES A. MANN.
